ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 497,711, dated May 16, 1893.

Application filed March 31, 1892. Serial No. 427.182. (N0 model.)

To all whom it may concern: Be it known that I, JOSEPH EARICH, a citizen of the United States of America, residing at Millfield, in the county of Athens and State of Ohio, have invented certain new and useful Improvements in Elevators, of which the following is a specification, reference being bad therein to the accompanying drawings.

This invention relates to that class of elevators which are adapted for use in the shafts of mines and are provided with tilting cages, and consists in certain improvements in the construction of such elevators, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 represents a side view of an elevator provided with my improvements. Fig. 2 is a sectional, plan View of the same. Fig. 3 is an endwise View. Fig. 4 is vertical central section showing cage tilted. Fig. 5 is a side view of car. Fig. 6 is a detail view of a weighted arm.

A designates the main frame to the opposite sides of which are secured the vertical guides B which extend from the top to the bottom. Another vertical guide B, which is beveled at the top, is fastened to the front part of the frame and extends upward to a plane where the dumping operation begins, as hereinafter set forth. WVithin the frame A is placed a cage which is provided with a platform C which is mounted in a vertical frame consisting of the opposite uprights D,

connected at the top by a bolster or cross-bar E, and a footpiece, F, secured to the lower ends of uprights D, the latter extending a suitable distance below the said platform. The said foot piece is secured by means of the long clips I) which extend over the top of the frame and down along the edges of uprights D, to which they are secured, and through the said foot piece, being secured by the nuts a and forming strengthening pieces for the cage frame.

The platform 0 has legs G which are bolted thereto and have boxings 0 formed on their lower extremities to receive the spindles of an axle d, which extend into said boxings, the said axle being mounted in bearings 0' made fast to the foot piece F. Truss-rods 0, connected with the platform and extending down under the grooved boxings c, serve to secure the parts firmly, said rods being provided with tightening swivels c.

On opposite edges of the platform 0, just forward of the uprights D, are the fixed guides f and, just at the rear of said uprights, are the pivoted latches g, the forward ends of which are turned inward in position to press against the weighted bent arms g which are loosely coupled to the platform at 9 for the purpose hereinafter stated.

As shown in Fig. 6, each of the arms 9 is suspended to the platform (I, having a hinge connection therewith, and is bent inward under the platform and carries a weight The vertical part of the arm g is in position to be pressed by a latch g, when the latter is pressed by a bulging plate J, so as to swing said arm inward, and when said latch is relieved from such pressure, the weighted arm by gravity is swung back again and presses thelatch outward.

The uprights D are provided with grooves, formed by the angle-irons h, fastened to said uprights, to receive the vertical guides 13.

The platform is provided with track-rails 2', on which a car loaded with coal or other mineral may be run to be elevated. Outside of the track-rails are located the horns or adjustable stops I which are pivotally coupled to the platform, at 0 and are provided with arms t extending downward from their pivotal connections. See Figs. 2 and 4. The said horns are bent somewhat inward and are also curved backward, so as to catch the forward wheels of a car run on the platform when the horns are in position over the rails. The horns I are connected, at their upper ends, by rods j with fixed eyes t"; said rods extend rearward and may be contracted or loosened. To the lower arms i of the horns I, a head it is connected by links t the said head being fast on one end of a shaft 7L2 which is mounted in bearings secured to the lower side of the platform. A lever 71 is secured to the rear end of the shaft 77.2 by which the shaft may be turned, so that the head it, being also turned, the horns I may be moved inward to catch the front wheels of the car, or turned outward from the rails.

On the platform 0, toward the rear, is pivoted a lever 75, and two bars on are arranged,

one on each side of lever 70, one of said bars being pivoted at its forward end to the platform, and the other, at its rear end, thereto. The opposite ends of bars m are connected with lever by links n, and pivotally connected with bars m about midway of said bars, are two keeper-blocks m which extend laterally outward under the guides at, so that, by a movement of the lever 70, the blocks m may be moved outward across the railst' to block the hind wheels of the car, or may be drawn inward to release said wheels. Asliphook s is connected with the platform, at the rear end, to be hooked to a draw-bar of the car, said hook serving to hold down the end of the car, and, with the blocks m, preventing any undue backward movement of the car when the platform, after being tilted forward, is swung back to its position. The platform has a roller q, mounted in its front end, which bears against the guide B, fixed to the front part of the frame A as the cage ascends, and another roller q is mounted in the rear end of the platform, the last mentioned roller being intended for contact with a tilting plate rsecured to the main frame in position to tilt the cage forward when the latter has reached the proper elevation, The

plate 0 is formed with an inclined surface and provided with slotted lugs, so that it may be adj ustably secured by bolts in position to the frame A. Each of the rollers, q, q, is faston a shaft extending into boxes 8 secured to the platform and found to be convenient for oiling.

H indicates two opposite plates forming guards or coal-catching devices which are intended to prevent coal from falling down the shaft frointhe loaded car, during the ascent,

of the latter in case the cribbing breaks. The lower edges of the plates H are turned inward to form catches 0, and said plates are made fast to the rods 9 which extend up from the platform and over the car when the latter is in place.

Two plates J, having inward bulging surfaces and provided with slotted lugs, are adjustably secured to opposite parts of frame A in position to pressinward the pivoted latches g as the cage rises and thus allow the cage to be tilted forward at the proper point.

The stops L are fastened to the top of the frame A in position to limit the movement upward of the cage. Such movement is effected by means of a cable passed over a pulley K mounted on the top of the main frame.

The loaded car being in place on the track, the horns I are moved inward by a movement of the lever h on shaft 71, and the hind wheels of the car are blocked by means of the keeper blocks on which may be extended by a movement of the lever 76, the car may be further secured by connecting the slip-hook s with the draw bar. The cage being raised by means of a cable connected with the cage frame, is tilted forward, when it reaches the proper elevation, by the rear tilting plate 0"; the end gate of the car, which is hung from the top, is released from its latches by means of the pivoted, hand-lever and is swung out and the contents of the car are discharged.

I claim- 1. The combination, with the main frame of an elevator, of the opposite bulging plates J, a vertical cage frame, a platformmounted therein, fixed guidesf made fast to said platform, pivoted latches g, bent inward as shown, bent arms g, in position to be pressed inward by the latches g, the said arms being under the platform and having hinge connections therewith, and weights g carried by said bent arms, substantially as set forth and described.

2. The combination with the platform of an elevator cage, provided with track rails, of a lever 75, pivoted to said platform, two bars m, one being at each side of the lever 70, and each being pivoted at one end to said platform, links a, connecting bars m with said lever, two keeper-blocks m, pivotally connected with bars m, and guides n for said keeper blocks, whereby said blocks may be moved outward across the track-rails, or may be drawn inward, substantially as and for the purposes described.

3. The combination with the platform of an elevator cage, and track rails secured thereto, of two curved horns Lpivotally connected with said platform, said horns being provided with arms i extending downward from their pivotal connections with the platform, two rods j, loosely connected with said horns and with said platform, a shaft 77?, located under said platform, in bearings carried by the latter, a lever h on one end of said shaft, a head 72., on the opposite end of said shaft, and links i which connect the opposite arms 2' of the horns I with the head it, whereby the said horns may be'moved outward from the track-rails, or inward over said rails, substantially as set forth and described.

In testimony whereof I have affixed my signature in presence of two witnesses.

JOSEPH EARIOH.
